8-10 high power shots (depending on how much ES you are willing to tolerate) from 3200 previously. 16 from 3000 now, but number 16 seems a little light in the thump department. If I have time today I'll shoot some Pro Chrono strings and see what the numbers tell me.

John at JDS is claiming he will have a 4500 to XXXX regulator available soon that will screw into the 250 bar bottles. That would really give some potential for shot counts once I finish adjusting and tuning to determine my best pressure to power efficiency.

Right now I am getting roughly 37 Hard hitting shots from a 3K 250BAR Bottle, those things are great, no regulator needed really!
